Ctrl + K expansion

So you know the Ctrl + K option when you get to choose like which chat or server. So one day I had the mouse far from me and I had the keyboard in my lap. I'm in like 30 different servers and I didn't know which server had the new messages. I could see it had new messages from the little red circle on the icon at the bottom in Windows. So all I'm asking for is that it shows you the chats that have a new messages in them; of course the unmuted ones.
